Google Using DoubleClick Tracking Cookies
dstates sends news coming out of the letters the House Energy and Commerce Committee sent to a number of broadband and Internet companies about their policies and practices on user tracking. The committee has now made public 25 responses to its queries, and many companies, including Google, acknowledge using targeted-advertising technology without explicitly informing customers. The Committee is considering legislation to require explicitly informing the consumer of the type of information being gathered and any intent to use it for a different purpose, and a right to say "no" to the collection or use. The submitter notes that, while Google denies using deep packet inspection, if the traffic is a Google search or email to or from a Gmail account, Google does not need DPI to see the contents of the message. "The revelations came in response to a bipartisan inquiry of how more Internet companies have gathered data on customers. Edward J. Markey (D-Mass.) said 'Increasingly, there are no limits technologically as to what a company can do in terms of collecting information... and then selling it as a commodity to other providers.' Some companies like NebuAd have tested deep-packet inspection with some broadband providers Knology and Cable One. Google said that it had begun to use the DoubleClick ad-serving cookie that allow the tracking of Web surfing across different sites but said it was not using deep packet inspection. Google promotes the fact that its merger with DoubleClick provides advertisers 'insight into the number of people who have seen an ad campaign,' as well as 'how many users visited their sites after seeing an ad.' Microsoft and Yahoo acknowledge the use of behavioral targeting. Yahoo says it allows users to turn off targeted advertising on its Web sites; Microsoft has not yet responded to the committee."
1. Turn off cookies globally.
2. Turn on cookies for sites that need it by hitting F12 and hitting 'Accept cookes only from the site I visit'.
Done. No more doubleclick cookies.

Did anyone really believe Google wasn't doing this?
And slashdot uses doubleclick & google-analytics as well.
Try disabling scripts with firefox "noScript". I think /. is more readable without allowing doubleclick.net & google-analytics.com
don't cut it off www.mgmbill.org
Ahem. STOP SPENDING MY TAX DOLLARS ON THIS CRAP.
Anyone using a computer who doesn't understand why they shouldn't accept all cookies and scripts and click on everything shiny deserves (yes, really!) to have their actions remotely monitored and the resulting data sold to the highest bidder.
I don't want to drown in regulation just because some idiots can't be bothered to pull their collective head out before they use their systems.
cogito ergo dubito
Ummm, isn't this exactly what we would expect them to do with all that information? The only people who should be surprised by this are the ones who have no idea how the internet works. That said, there are plenty of workarounds, including limiting accepted cookies only to sites you specify, or having your browser clear everything out upon closing. Sure it doesn't totally fix the problem (assuming you consider it a problem), but it certainly does limit the amount of tracking they can do.
This guy's the limit!
"Don't Do Eval". not "Don't Do Evil". The guys at Google wanted to make sure all the employees wouldn't use the eval command to create possible security holes by executing string.
If something is so important that you feel the need to post it on the internet... It probably isn't that important.
Google makes it easy to opt out of the doubleclick tracking cookie:
http://www.google.com/privacy_ads.html
"Anyone may opt out of the DoubleClick cookie (for both the Google content network and DoubleClick ad serving) at any time by clicking the button above."
Google's targeted advertisements seems reasonable; When you decide to use their free services, you should know that advertising is a part of the deal.
Broadband providers using DPI, on the other hand, is like the USPS opening your private mail and then profiting off of what they learn about you. It's all about the expectation of privacy. Broadband providers need to transfer bits and stay out of the content business. If they start doing this, there will be no way to use the internet with any modicum of privacy.
You see, they don't just get the cookie, they also get the referrer field, so Google doesn't just get to see that it is "Nicholas Weaver" who's surfing the web, but can see that I am composing a reply to this article, because the referrer field in the doubleclick adds and google analytics on slashdot allow them to know this!
Test your net with Netalyzr
Or use Firefox and uncheck Accept third-party cookies in the Privacy Options. Or use Internet Explorer and block third-party cookies. Or use Safari and disallow third-party cookies. I don't see any reason to switch browsers just to access a basic feature.
What a fool believes, he sees, no wise man has the power to reason away.
>> their motto is "Don't be evil"
...where "don't be" approaches "be" for some values of evil.
They added the function again in firefox 3.0, so it is again possible to block third-party cookies without any extensions or other software than just a fresh firefox installation.
